More widely distributed and abundant than L. aspent, and characterised by 

 considerable variation, chiefly in the length of the neck which, in the deep-water 

 Stations 16, 18. 19, 20, is very pronoiniced. Specimens with a complete armatiire 

 of long fine spines, such as we find in the North Sea, do not occur. The spmes 

 as a rule are very short, sometimes amounting to nothing more than a matt 

 surface to the test. At Station 16 some abnormal individuals isomorphous witli 

 L. apiculata and finely hispid were found. 



292. Lagena chvulus, sp. nov. PL V, fig. 7. 



Station 29. 



Test elongate, pyriform, without a produced neck. The entire surface closely 

 covered with bolt-like projections of uniform length, set in close parallel rows in 

 the direction of the long axis of the test. Every protuberance has a slightly 

 swollen extremity like the head of a nail, flat upon the outer surface. 



Dimensions: — Length, •2.5mm.; l)readth. •12mm. 



The species is based on a single individual which is, however, so characteristic 

 in appearance as to deserve special notice. It may be merely a highly distinctive 

 variation of L. hispida, or it may represent a form in process of transition into 

 the group of double-walled Lagenae of the L. foreolata group. There are faint 

 indications of a delicate pellicle between some of the " studs " which give support 

 to tlie latter theory.

 Examples with a spinous base at Station 17. Very small at Station 55. At 

 Station 48 a variety occurs in which certaui of the costae are developed to a 

 greater extent than the intervening ones, so as to separate the shell into a
